Introduction
Pruritus (itching) of the skin is commonly observed in patients with lymphoma, particularly in those with Hodgkin lymphoma. Hodgkin lymphoma predominantly affects young adults, while it is rare in children. The most common initial symptom is progressive, painless enlargement of cervical or supraclavicular lymph nodes; axillary lymphadenopathy is the next most frequent presentation. Enlarged lymph nodes may be mobile or may adhere to one another and coalesce into masses. Other systemic symptoms include fever, night sweats, pruritus, and weight loss.
Lymphoma is broadly classified into two major categories: Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL). In the case of Hodgkin lymphoma, the cure rate typically exceeds 80–90%. For non-Hodgkin lymphoma, certain indolent subtypes—such as follicular lymphoma, chronic lymphocytic leukemia (CLL), and small lymphocytic lymphoma—are generally considered incurable. In contrast, aggressive lymphomas—most commonly diffuse large B-cell lymphoma (DLBCL)—are potentially curable with intensive treatment. So, does lymphoma cause pruritus (itching)? The following section addresses this question.
Does lymphoma cause skin itching?
Pruritus is relatively common in patients with Hodgkin lymphoma. HL predominantly affects young adults, with rare occurrence in children. The most frequent initial symptom is painless, progressive enlargement of cervical or supraclavicular lymph nodes; axillary lymphadenopathy may follow. Enlarged lymph nodes are often mobile but may also adhere to one another and coalesce into larger masses. Systemic “B symptoms”—including fever, night sweats, pruritus, and unintentional weight loss—are frequently observed. A subset of patients develops localized or generalized pruritus, particularly younger women.
In some cases, pruritus may be the sole systemic manifestation of Hodgkin lymphoma. By contrast, while non-Hodgkin lymphoma also commonly presents with painless, progressive cervical or supraclavicular lymphadenopathy, pruritus is comparatively uncommon in NHL patients.
Furthermore, systemic intravenous chemotherapy remains the cornerstone of treatment for malignant lymphomas. However, chemotherapy carries inherent toxicities, including myelosuppression and, in severe cases, hepatic or renal dysfunction. Therefore, early diagnosis and prompt medical intervention are strongly recommended.
